background: the effect of probiotic bacteria ( lactobacillus acidophilus and l. casei ) as safe organisms was examined on fungal growth and aflatoxin gene regulation in aspergillus parasiticus . methods: the fungus was cultured in presence of two different concentrations of l. acidophilus and l. casei in mrs broth medium. mycelia dry weight is indicated as criteria to evaluate fungal growth. be...

Prebiotik merupakan suatu komponen bahan pangan yang tidak dapat dicerna oleh pen-cernaan manusia, namun dimanfaatkan sebagai nutrisi pertumbuhan bagi microflora usus serta mampu memberikan manfaat kesehatan. Inulin dan fruktooligosakaridan (FOS) adalah jenis prebiotic banyak dikembangkan untuk saat ini. Review ini bertujuan mengetahui (1) potensi inulin FOS prebiotik, (2) bakteri asam laktat t...

Four lactobacilli strains (Lactobacillus bulgaricus, Lactobacillus acidophilus, Lactobacilus casei and Lactobacillus reuteri) were grown in MRS broth and three lactococci strains (Streptococcus thermophilus, Lactococcus lactis subsp. Lactis and Lactococcus lactis subsp. lactis biovar. diacetilactis) were grown in M17 broth. L. reuteri and S. thermophilus were chosen on the basis of the best mea...

LactobaciUus bifidus (Lactobacilus acidophilus ATCC 4963) was previously reported (Skeggs et al., 1949) to require for growth, in an otherwise complete medium, either vitamin B12, thymine desoxyriboside, or intact desoxyribonucleic acid (DNA). The growth of L. bidus in the presence of DNA was found (Skeggs et al., 1950)1 to be inhibited competitively by yeast ribonucleic acid (RNA). Subsequent ...

Lactobacillus acidophilus is a commercially significant bacterial probiotic, originally isolated from the human gastrointestinal tract and designated Bacillus acidophilus in 1900. Throughout the development of methods to identify and characterise bacteria, L. acidophilus has undergone multiple taxonomic revisions and is now the type species of a phylogenetic subgroup in the highly diverse and h...

Lactic acid bacteria were isolated from piglets and chicken and characterized. Lactic acid bacteria showing resistance to low pH and bile, adhesion to intestinal epithelium cells, and the inhibition of Escherichia coli and Salmonella spp. were identified as Lactobacillus acidophilus. L. acidophilus PF01 survived for 2 h in MRS broth adjusted to pH 2. L. acidophilus CF07 was less resistant than ...

It has been observed that Lactobacillus acidophilus has poor survivability in fermented goats’ milk. In this study, interactions between L. acidophilus and starter cultures during goats’ milk fermentation were investigated using three strains of L. acidophilus: ATCC-11975, LA-5 and NCFM, and the starter cultures (Lactobacillus delbrueckii subsp. bulgaricus (LB350) and Streptococcus thermophilus...
